Editing Werewolf: The Forsaken (section)

===Idigam===
But perhaps the most dangerous are the Idigam, the spirits who embody concepts that existed and faded away long before the world was fully formed. To survive, they became the incarnations of chaos and gained the ability to mimic the characteristics of anything mortal or spiritual. Between that and their unmatched ability to manipulate Essence, even Father Wolf was unable to slay them. Instead, they were sealed away on the moon where there was nothing for them to copy; Luna saw to that when she bound them in a prison as formless as they were. However, a relatively recent internecine war among the werewolves gave them an opportunity to escape back to Earth during the first manned moon landings. And they're VERY interested in making up for lost time now that they're back on Earth- as are the alien spirits that they've encountered and allied with during their banishment and the armies of minions they can create by corrupting other spirits with their Essence.
